aging, transport and storage
Your instrument was protected by packaging during transport. Its capacity to handle normal loads during transport is assured by a test according to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly, recyclable cardboard. For special versions, PE foam or PE foil is also used. Dispose of the packaging material via specialised recycling companies.
Transport must be carried out under consideration of the notes on the transport packaging. Nonobservance of these instruc­tions can cause damage to the device.
The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and stored according to the orientation and storage markings on the outside.

4.1 General instructions

Select
an installation position you can easily reach for
mounting and connecting as well as later retrotting of an indicating and adjustment module. The housing can be rotated by 330° without the use of any tools. You can also install the indicating and adjustment module in four dierent positions (each displaced by 90°).
Before beginning the welding work, remove the oscillator (electronics) from the sensor. By doing this, you avoid damage to the electronics through inductive coupling.
With threaded versions, the housing must not be used to screw in the instrument! Applying tightening forces on the housing can damage its internal parts.
Use the hexagon for screwing in.
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your instrument additional protection against moisture penetration by leading the connection cable down­ward in front of the cable entry. Rain and condensation water can thus drain off. This applies mainly to outdoor mounting as well as installation in areas where high humidity is expected (e. g. through cleaning processes) or on cooled or heated vessels.

Keep in mind that the cable length cannot be used all the way to the end because measurement in the area of the gravity weight is not possible. These min. distances (dead bands) are listed in chapter "Technical data".
Pressure
Mounting position
The process tting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the seal material is resistant against the measured product and the process temperature.
The max. permissible pressure is specied in chapter "Technical data" or on the type label of the sensor.

4.2 Mounting instructions

Mount VEGAFLEX 66 in such a way that the distance to vessel installations or to the vessel wall is at least 300 mm (12 in).
During operation, the probe must not touch any installations or the vessel wall. If necessary, fasten the probe end.
In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the bottom. When using the cable version, keep in mind that measurement down to the tip of the probe is not possible. The exact value of the

Standpipes or bypass tubes are normally metal tubes with a diameter of 30 … 200 mm (1.18 7.87 in). In measurement technology such a tube corresponds to a coax probe. It does not matter if the standpipe is perforated or slotted for better mixing. Lateral inlets with bypass tubes also do not inuence the measurement.
Measuring probes can be mounted in bypass tubes up to DN 200.
The max. temperature is 250 °C (482 °F).
If VEGAFLEX 66 is used in standpipes or bypass tubes,
contact with the tube wall should be avoided. We oer spacers as accessories for fastening the probe in the middle of the tube.
Depending on the tube diameter or tube length, one or several spacers can be mounted. With cable probes, the cable can also be strained to avoid contact with the tube.
The max. temperature for the spacers is 250 °C (482 °F).
A special high temperature version of VEGAFLEX 66 with
integrated bypass tube can be used in applications with temperatures up to 400 °C (752 °F).

Excessive system vibration or shocks, e.g. caused by agitators or turbulence in the vessel (e.g. from uidisation) can cause the coax probe of VEGAFLEX 66 to vibrate in resonance. Should a coax probe of more than 1 m (3.281 in) length should be used, you can provide a suitable support or guy directly above the end of the probe to stabilise it.
If there is a danger of the probe touching the vessel wall during operation due to product movements or agitators etc., the measuring probe should be securely xed.
In the gravity weight there is a thread (M12), e.g. for a ring bolt (article no. 2.27424).
Make sure that the probe cable is not completely taut. Avoid tensile loads on the cable.
Avoid undened cable-vessel connections, i.e. the connection must be either grounded reliably or isolated reliably. Any deviation from this requirement can lead to measurement errors.
VEGAFLEX 66 should be integrated in the vessel installation. This prevents the electronics from strong heating by heat
radiation.

Tip:
We
recommend VEGA overvoltage arrester B63-32.
In
hazardous areas you should take note of the appropriate
regulations, conformity and type approval certicates of the sensors and power supply units.
Power is supplied via a Probus DP/PA segment coupler or a VEGALOG 571 EP input card. The power supply range can
dier depending on the instrument version.
Data for power supply are specied in chapter "Technical data".
Connection is made with screened cable according to the Probus specication. Power supply and digital bus signal are
carried over the same two-wire connection cable.
Use cable with round cross-section. A cable outer diameter of 5 9 mm (0.2 0.35 in) ensures the seal eect of the cable gland. If you are using cable with other diameter or cross­section, you have to exchange the seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the Probus specication. In particular, make sure that the termination of the bus is done with appropriate terminating resistors.

Cable screening and grounding
Select connec­tion cable for Ex applications
In systems with potential equalisation, connect the cable screen directly to ground potential at the power supply unit, in the connection box and at the sensor. The screen in the sensor must be connected directly to the internal ground terminal. The ground terminal outside on the housing must be connected to the potential equalisation (low impedance).
In systems without potential equalisation, connect the cable screen directly to ground potential at the power supply unit and at the sensor. In the connection box or T-distributor, the screen of the short stub to the sensor must not be connected to ground potential or to another cable screen. The cable screens to the power supply unit and to the next distributor must be connected to each other and also connected to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The low frequency potential equalisation currents are thus suppressed, but the protective eect against high frequency interference signals remains.

6.4 Setup
procedure
After VEGAFLEX 66 is connected to voltage supply or after voltage recurrence, the instrument carries out a self-check for approx. 30 seconds. The following steps are carried out:
l Internal l Indication of the instrument type, the rmware
check of the electronics
as well as
the sensor TAGs (sensor designation)
l Status byte goes briey to fault value
Then the current measured value will be displayed and the corresponding digital output signal will be outputted to the
1)
cable.
Before starting the actual parameter adjustment of a P
robus
PA sensor, the address setting must rst be carried out. You will nd a detailed description in the operating instructions manual of the indicating and adjustment module or in the online help of PACTware or DTM.
As VEGAFLEX 66 is a distance measuring instrument, the distance from the sensor to the product surface is measured. To have the real product level displayed, an allocation of the measured distance to the percentage height must be made. To carry out this adjustment, the distance is entered with full and empty vessel. If these values are not known, an adjustment with the distance values, e.g. 10 % and 90 % is also possible. Starting point for these distance specications is always the seal surface of the thread or ange. With these settings, the real level is calculated. Furthermore the operating range of the sensor is limited from maximum to the required range.
The real product level during this adjustment is not important, because the min./max. adjustment is always carried out without changing the product level. These settings can be made ahead of time without the instrument having to be installed.
In the main menu item "Basic adjustment", the individual submenu items should be selected one after the other and provided with the correct parameter values.
Caution:
there is a separation of dierent liquids in the vessel, e.g. by
If condensation, VEGAFLEX 66 will always detect the medium with the higher dielectric gure

Each product has dierent reective properties. In addition,
there are various interfering factors which have to be taken into account: agitated product surfaces and foam generation (with liquids); dust generation, material cones and echoes from the vessel wall (with solids). To adapt the sensor to these dierent conditions, you should rst select in this menu item under "Medium" the selection "Liquid" or "Solid".
With coax versions, this menu item must be set to "Liquid".
Application
Liquid
Standard (DK 2)
Depending on the dielectric gure (dielectri value or εr), measured products can have a dierent reective property.
Therefore an additional selection possibility is available.
Under "Sensitivity" you can select "Standard (DK 2)" or
"Increased sensitivity (DK < 2)".
Through this, the sensor is adapted perfectly to the product and measurement reliability, particularly in products with bad reective properties, is considerably increased.
Enter the requested parameter via the appropriate keys, save your settings and jump to the next menu item with the [->] key.
Damping
To suppress uctuations in the measured value display, e. g. caused by an agitated product surface, an integration time can be set. This time can be between 0 and 999 seconds. Keep in mind that the reaction time of the entire measurement will then be longer and the sensor will react to measured value changes with a delay. In general, a period of a few seconds is sucient to smooth the measured value display.

Linearisation curve
A linearization
is necessary for all vessels in which the vessel
volume does not increase linearly with the level - e. g. with a cylindrical or spherical tank - and the indication or output of the volume is required. Corresponding linearization curves are preprogrammed for these vessels. They represent the correlation between the level percentage and vessel volume. By activating the appropriate curve, the volume percentage of the vessel is displayed correctly. If the volume should not be displayed in percent but e.g. in l or kg, a scaling can be also set in the menu item "Display".

Caution:
Note
the following, if VEGAFLEX 66 is used as part of an
overll protection system according to WHG:
If a linearisation curve is selected, the measuring signal is no longer compulsorily linear proportional to the level. This must be taken into consideration by the user, particularly when adjusting the switching point on the level switch.
Sensor-TAG
In this menu item you can enter an unambiguous designation for the sensor, e.g. the measurement loop name or the tank or product designation. In digital systems and in the documen­tation of larger plants, a singular designation should be entered for exact identication of individual measuring sites.

Gating out of false sig­nals
High sockets or vessel installations, such as e. g. struts or agitators as well as buildup and weld joints on the vessel walls cause interfering reections which can impair the measure­ment. A false echo storage detects and marks these false echoes, so that they are no longer taken into account for the

e echo memory should be created
with empty vessel so that all potential interfering reections will be detected.
Probes in coax version require no gating out of false echoes since they are not inuenced by false reections.

Note:
Check
the distance to the product surface, because if an incorrect (too large) value is entered, the existing level will be saved as false signal. The lling level would then no longer be detectable in this area.

10.2 Probus P
A
Instrument master le
The instrument master le (GSD) contains the characteristic data of the Probus PA instrument. These data are, e.g. the permissible transmission rates as well as information on diagnostics values and the format of the measured value outputted by the PA instrument.
A bitmap le is also provided for the Probus network planning tool. This le is installed automatically when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instrument in the conguration tool.
Ident number
Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user organisation (PNO). This ID number is also included in the name of the GSD le. For VEGAFLEX 66 the ID number is 0 x 0771(hex) and the GSD le FX__0771.GSD. Optionally to this manufacturer-specic GSD le, PNO provides also a general so-called prole-specic GSD le. For VEGAFLEX 66 you have to use the general GSD le
PA139700.GSD. If the general GSD file is used, the sensor must be set to the prole­specic ident number via the DTM software. By default, the sensor operates with the manufacturer-specific ID number.
Cyclical data trac
The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during operation. The below block diagram below shows which data can be accessed by the PLC.

Module of the PA sensors
For the cyclic data trac, VEGAFLEX 66 provides the following modules:
l AI (PA-OUT)
- PA-OUT value of
l Additional Cyclic Value
- Additional cyclical value (depending on the source)
l Free Place
- This module must be used if a value should not be used in the data telegram of the
cyclical
Max. three modules can be active. By means of the conguration software of the Probus master, you can determine the conguration of the cyclical data telegram with these
data trac (e.g. replacement of the Additional Cyclic Value)

modules. The procedure depends on the respective conguration software.

The status byte corresponds to prole 3.0 "Probus PA Prole for Process Control Devices" coded. The status "Measured value OK" is coded as 80 (hex) (Bit7 = 1, Bit6 … 0
= 0).
The measured value is transferred as a 32 bit oating point number in the IEEE-754 format.
